REVIEW
Anne L Schafer
Bariatric surgery is a highly effective treatment for obesity, but it may have detrimental effects on the skeleton. Skeletal effects are multifactorial but mediated in part by nutrient malabsorption. While there is increasing interest in non-nutritional mechanisms such as changes in fat-derived and gut-derived hormones, nutritional factors are modifiable and thus represent potential opportunities to prevent and treat skeletal complications. This review begins with a discussion of normal intestinal calcium transport, including recent advances in our understanding of its regulation by vitamin D, and areas of continued uncertainty...

Bariatric surgery is one of the most common surgeries within developed countries due to the increase in morbid obesity that has been observed in the past decades. The short-term alterations in the metabolism of calcium and vitamin D are well known after these procedures; however, the clinical and biochemical consequences may not be detected for years or even remain undiagnosed. We present the first case of bilateral insufficiency hip fracture after years of bariatric surgery. Although this is a long-term and rare complication, with the high number of gastric bypass performed in the past years, the number of these cases could increase with time...

Professional cooperation protocols have recently been developed by the French national health authority and regional health agencies. They enable paramedical staff to perform procedures usually carried out by doctors. In the framework of bariatric surgery, the follow-up of patients after surgery is thereby assured by specialist nurses. They can make a diagnosis and prescribe vitamins, minerals and tests.

Roughly 1% of all weight loss surgery is performed in adolescents. There is strong evidence demonstrating significant postsurgical weight loss, improvement in quality of life, and reduction in comorbidities such as hypertension and diabetes. Reports of postoperative complications in adolescents are few because of the small sample size in most series. Despite vitamin supplementation, nutritional deficiencies requiring hospitalization occur occasionally after Roux-en-Y gastric bypass. Wernicke encephalopathy, a triad of ophthalmoplegia, ataxia, and altered mental status, is a serious consequence of thiamine (vitamin B1) deficiency...

BACKGROUND: Robust data on quality of life (QoL) after different techniques of bariatric surgery are sparse. This RCT compared excess weight loss (EWL) and QoL after sleeve gastrectomy versus Roux-en-Y gastric bypass (RYGB). METHODS: Obese patients were assigned randomly to RYGB or sleeve gastrectomy. The primary outcome measure was EWL. Secondary outcomes included QoL, co-morbidity, adverse events, vitamin and glycolipid status. QoL was assessed before and annually after surgery, using the Moorehead-Ardelt Quality of Life Questionnaire II (M-A-QoLQII) and Gastrointestinal Quality of Life Index (GIQLI)...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has gained popularity as the leading bariatric procedure for the treatment of morbid obesity. Due to the rising numbers of bariatric surgeries, neurologic complications have become increasingly recognized. Our aim was to examine biochemical and hormonal factors that are associated with neuropathy post-LSG. METHODS: Thirty-two patients were included: 16 patients with neuropathy in the neuropathic group (NG) and 16 patients without neuropathy in the control group (CG)...

Bariatric surgery is associated with bone loss but skeletal consequences may differ between Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), the two most commonly performed bariatric procedures. Furthermore, severe weight loss is associated with high marrow adipose tissue (MAT); however, MAT is also increased in visceral adiposity. The purpose of our study was to determine the effects of RYGB and SG on BMD and MAT. We hypothesized that both bariatric procedures would lead to a decrease in BMD and MAT...

BACKGROUND: Vitamin D deficiency (VDD) is associated with obesity and metabolic syndrome (MS). After bariatric surgery (BS), high rates of VDD often persist and some patients are refractory to the resolution of comorbidities. The aim of the present study is to analyse the relationship between the levels of vitamin D and the persistence of MS components at 12 months after BS, according to the surgical technique used. METHODS: We performed a retrospective study of 46 patients undergoing BS: 23 underwent laparoscopic Roux-en-Y gastric bypass (LRYGBP) and 23 laparoscopic sleeve gastrectomy (LSG)...

OBJECTIVE: Our objective was to compare the ECLIA from Roche versus the LC-MS/MS method for quantitation of serum 25-hydroxy-vitamin D in patients who have undergone bariatric surgery. DESIGN AND METHODS: Cross-sectional and correlational studies were performed on three different groups for the 25-OH-D levels quantitated by both methods. The control group of apparently healthy subjects was randomly selected in a clinical chemistry laboratory. Test groups were patients who had undergone bilio-pancreatic diversion (BPD) and were supplemented either with vitamin D2 or with vitamin D3...

INTRODUCTION: Hyperhomocysteinemia is a biological marker that could be identified in the venous thrombotic events and rarely during acute arterial thrombotic events. The consequences can be serious. Effective diagnostic strategy is needed to optimize the management. CASE REPORT: Following bariatric surgery, a 40-year-old patient was admitted with an acute encephalopathy associated with peripheral lower limb arterial ischemia. The diagnostic work-up identified a major hyperhomocysteinemia whose causes were several...

BACKGROUND: Bariatric patients often suffer from vitamin D deficiency (VDD), and both, morbid obesity and VDD, are related to non-alcoholic fatty liver disease. However, limited data are available regarding best strategies for treating VDD, particularly, in bariatric patients undergoing omega-loop gastric bypass (OLGB). Therefore, we examined the efficacy and safety of a forced vitamin D dosing regimen and intervention effects in liver fibrotic patients. METHODS: In this double-blind, randomized, placebo-controlled trial, 50 vitamin D-deficient patients undergoing OLGB were randomly assigned to receive, in the first month postoperatively, oral vitamin D3 (≤3 doses of 100,000 IU; intervention group) or placebo as loading dose (control group) with subsequent maintenance dose (3420 IU/day) in both groups until 6-month visit...

With the rise of obesity there has been a concomitant increase in the incidence of type 2 diabetes (T2DM). As a result, the term "diabesity" has become a popular disease entity in the past several years. When lifestyle modification and pharmacotherapy fail to achieve successful weight loss and diabetes control, bariatric surgery is a recommended treatment option. Bariatric surgery has been shown to promote sustained T2DM remission in 30-63% of patients and improve other components of metabolic syndrome; thus a preferred term has been "metabolic surgery"...

BACKGROUND: Hypocalcemia is a common complication after total thyroidectomy. Previous bariatric surgery could be a higher factor risk for hypocalcemia due to alterations in calcium absorption and vitamin D deficiency. OBJECTIVES: To evaluate incidence and factors involved in the risk of hypocalcemia (transient and permanent) and the postoperative outcomes of these patients after total thyroidectomy. SETTING: University hospital in Paris, France...
